s3c24xx gpiolib question

[Vasily Khoruzhick]

Hi,

Is following patch sufficient to add GPJ port support to s3c24xx gpiolib?
And how to switch gpioline to custom function mode (for example TOUT0 on GPB0) 
via gpiolib?

I need to get the gpio number space compressed to get this to
work, it got shuffled out of this round of patches due to urgent
meetings.
